I'm not sure... the project management seems to be written in a special
C++ variant with garbage collection ;-)

Because perl is such a convoluted mess that only L.W. can write
a parser for it :-) [1]

I assume you mean two parsers, not two class browsers? It's perfectly
possible to have many class browsers [2]. If you want to support several
languages in the same project, you have to rethink everything related
to the sourceinfo anyway. You can't just let several different parsers
put their stuff into the same class store, because you must be able
to distinguish classes written in different languages (e.g. for the
'Add method' menu item). So you must have several class stores and
you must be able to distinguish them. It's possible to extend the
framework in this way. It's possible to extend other frameworks in
this way. But you will never get support for that automagically
in either of them.

[1] Hey, I _love_ perl :-)
[2] Two months ago, I had another one. Unfortunately, I was stupid
    enough to do a 'make cvs-clean' without having investigated
    what it actually does :-(((( I still have shivering hands whenever
    I think about rewriting it...
